These doors connect homeowners to bright environments and allow natural light into the home while saving on utility cost by not having to turn on the lights during the day.

Sliding doors also make homes look more inviting, welcoming, and spacious. But to complete the look of these contemporary doors, homeowners should consider installing curtains on them.

There are many curtain ideas to find online, but it is important to measure the door before choosing the right curtain treatments. This will help homeowners find practical and attractive curtains to complement their interior decor and sliding glass door. 

So after taking the measurements of the door and right before jumping into a design, pattern, and style for a sliding glass door curtain, one has to determine the important sizes of a curtain. It’s also important to consider curtain rods and the number of curtain panels needed.

What Size Curtains For Sliding Glass Door?

Sliding glass door curtain sizeThe most common sliding door size is five or six feet, translating to a 60-inch width or 72-inch width. Most often it will be six feet or 72 inches.

To determine the size of the curtain panel you need, add four inches to every side to leave a slight overhang distance so that you can push the curtain back from your doorway easily. For this, you’ll come up with a width of 80 inches for a 6-foot door width.

Or, you can just measure the width of the door and then divide it by the number of panels. Once you have the calculations, you can multiply the result for the desired fullness, if you have one (regular drapes, 1; drapes that heavily pleat when they’re pushed back, 2 or 3).

For an 80-inch wide door, which is divided by four panels and with a regular fullness, your curtain panel must be 20 inches wide each and should be 84 inches long.

For an 80-inch wide door that’s to be installed with two panels and with a regular fullness, every panel should be 40 inches wide and 84 inches long.

For four panels having double fullness, choose curtain panels that are 40 inches wide and should be 84 inches long. For two panels and double fullness, you can have 80-inch curtain panels for each and should be 84 inches long.

If you’ve already decided on the number of panels to use for sliding glass doors, you should also think about the fullness look you want to achieve for your curtains. Some homeowners prefer covering the door completely or getting a curtain panel that is twice the size they need, making the curtain drapes appearing plush.

However, one must also take note that it can be cumbersome to have additional material to the curtain at the same time. Thus, it would help to pick a simple curtain.

Standard Sliding Door Curtain Size

You can start measuring from the top of the door to the bottom to ensure getting the right measurements of the door’s height and check that yours is a standard height.

The width of a standard sliding glass door is five feet or six feet or 60 inches or 72 inches, but many are 6 feet wide.  But if you can’t eyeball this, get a measuring tape to double check. Once you’ve determined the length and width, you can start choosing curtain fabrics and curtain rods.

Standard two-panel sliding glass doors measure 72 inches. So for the curtain size, each must extend 3 inches above the frame of the door and then 1 inch just below the door frame. This will allow the curtains to graze the floor while not covering the top of the frame.

It means that a curtain that is four inches longer than the height of the door, which is 80 inches, is what you need. Thus, 84-inch sliding glass door curtains are what you should get.

Nevertheless, sliding glass door curtains typically measure the standard 84 inches or the large 96 inches. Ensure that the curtains are framing the sliding doors for a stylish and functional look.  They must also extend four inches past the door and then two inches on each side.

How Many Curtain Panels For A Sliding Glass Door?

Sixty to seventy two inches is the typical sliding glass door size and most rods will have a support center post, which is a requirement for rods that are longer than 60 inches. A curtain can’t slide between the center post, so you’ll need one curtain panel to cover each side.

Meanwhile, some homeowners prefer traverse curtains that aren’t limited by a center post. The curtain for traverse rods are called pinch pleats. For this, you could have one curtain panel, which can be easily pushed off to the side when you want to.

Then, there are people that use four panels that allow arrangement of multiple panels that can block sunlight, but if your sliding glass door is used frequently, moving your curtain panels aside might be a burden.

Meanwhile, there are homeowners opting for a unique three-panel curtain, as they can add more visuals versus one or two-panel curtains. This gives them more freedom in terms of choosing the right amount of light to enter their homes based on the sun’s position.

Many three-panel curtains also have medium thickness, allowing light to still shine through even when closed, unlike blackout curtains that can make a space appear dark or sheer curtains that don’t provide sun shade. For more details visit our guide to layered curtains here.

How Long Should Curtains Be For A Sliding Door?

Another important measurement to take when considering sliding glass door curtains is the length of the curtain itself. A curtain’s size is measured and determined by the dimensions of the sliding glass door. So as standard door frames are 80 inches in height, a curtain panel should be 84 inches in height. 

How Do You Calculate Curtain Size For Sliding Door?

To determine the size of the curtain for a sliding door, calculate the correct panel width through measuring the door frame’s diameter from each outer edge. One can easily do it, though.

• Add five inches to a 60-inch wide door for a curtain 65 inches wide.
• For doors wider than 72 inches, you can add eight to 12 inches to the width of the door.
• For an 80-inch wide curtain panel, you can just add eight inches to a 72-inch wide door.
• NOTE: Wider doors would need greater stacking distance.

What Size Curtain Rod For Sliding Glass Door

Curtain rod size for sliding doorAs the standard length of sliding glass doors is either 60 or 72 inches, the curtain rod you’ll need should extend from 3 to 6 inches on either side. If you have the common 72-inch or 6-foot sliding door, your curtain rod size should be from 78 inches to 84 inches.

On the other hand, it must measure from 66 to 72 inches if your sliding glass door is 60 inches or five feet.

For irregularly sized doors, add three to six inches on each side. Remember, there are also curtain rods with fixed length, although others will have springs inside. This allows adjustments for the desired length.

Homeowners should also consider getting the correct curtain rod diameter because it will look cheap and might break if the curtains are heavy if it’s less than one inch.
